Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed November 1, 1902. Serial No. 129,680.

To all whom it may concern.-

Beitknown that I, JosErH DAIN, a citizen of the United States, and aresident of Ottumwa, in the county of Wapello and State of Iowa, haveinvented certain new and useful Improvements in Hay-Presses, of whichthe following is a specification, reference being had to theaccompanying drawings.

This invention relates to baling-machines, and is primarily designed foruse in compressing hay into bales, and is of the type employing apull-bar for operating the compressing head or follower as distinguishedfrom that type in which the head or follower is moved by a push impartedthrough the connectingrod from the usual horse --power. In machines ofthis type it has heretofore been deemed necessary to employ a more orless complicated system of levers, through which the power wastransmitted, in order to suitably move the head or follower, suchmechanism being deemed necessary owing to the inability to make a properdirect connection of the pull-bar with the head or follower.

The object of my invention is to provide a construction whereby a directconnection of the pull-bar to the head or follower can be made whichwill be sufiiciently strong to insure such head or follower compressingthe material in the baling-case to the required extent and at the sametime to so locate the pullbar that it may extend in a direct line towardthe horse-power and yet not interfere with the free compression of thematerial in the baling-case. To this end I provide the bottom of thebaling-case with a central longitudinal slot through which theconnection between the head or follower and the pull-bar can move.Inasmuch as a ridge or rib of the material being compressed would be aptto be formed upon the bale by reason of being forced down through suchslot in the bottom of the baling-case during the compression of suchmaterial, I guard against such formation by providing the upper face ofthe connection between the pull-bar and the head or follower with araised central portion, which enters such slot and lies substantiallyflush with the face ofthe bottom of the baling-case.

That which I regard as new will be set forth in the claims.

In the drawings, Figure 1 is a longitudinal section at line 2 2 ofFig. 1. Fig. 3 is an end View, and Fig. 4 is an enlarged cross-sectionat line 4 4 of Fig. 1.

Referring to the drawings, 5 indicates a baling-case, to the upper sideof which near one end is a hopper 6, through which the hay or othermaterial to be compressed can be fed into the interior of the case 5.The baling-case shown is of ordinary construction, with the exceptionthat it has formed in its bottom a central longitudinal slot 7, whichextends to a greater or less degree under that portion of the case inwhich the hay is compressed, which for convenience will be termed thebalingchamber.

8 8 indicate channel-irons suitably secured below the bottom of thebaling-case 5 at each side of the central longitudinal slot 7.

9 9 10 indicate a slide which acts as a con.- nection between thepull-bar of the machine and the head or follower, the part 10 beinginterposed between and suitably secured to the parts 9 and such centralpart 10 extend ing above the upper faces of the parts 9, so as to enterand close the longitudinal slot 7 as best shown in Fig. 4.

11 indicates the compressing-head or follower, located in thebaling-case 5 and having a rearwarolly-extending central web 12. Thisweb 12 in the construction shown is formed integrally with the part 10,although of course it might be made separate therefrom and suitablysecured thereto.

13 13 indicate a pair of rollers, each suitably journaled at one side ofthe web 12 and adapted to roll upon the floor of the balingcase. 14 14indicate another and smaller pair of rollers carried near the forwardends of the pieces 9 9 of the slide and traveling within thechannel-irons 8. With the device in use and the head or follower 11pressing with great force against the material to be compressed withinthe baling-case it will be evident that the force exerted will tend tocause the forward ends of the pieces 9 to rise, and by the provision ofthese rollers 14 14 at such ends such rollers will bear against theupper turned portions of the channel-irons 8, and thereby greatly lessenfriction between the parts.

15 indicates the pull-bar, which may be of the ordinary form for suchpull-bars or any other equivalent construction and which is connected tothe slide 9 9 10 by any suitable means, the means shown being a hook 16on the rear end of the pull-bar l5 and an eye 17,'

power and the head or follower 11 drawn forward, compressing the hay orother material fed into the case 5 through the hopper 6 and that atregular intervals and in the usual manner the ordinary trippingmechanism of the horse-power will release the pull on the pull- 15 barand that thereupon such pull-bar and attached parts will through theaction of the compressed material in the case 5 be forced back so thatthe head or follower will be in position to receive in front of itanother charge of material, which in turn will be forced forward in thebaling-case. The rebound of the pull-bar and the head in all machines ofthis class is very sudden, and when the connection between the pull-barand the head or follower z5--isbymeans of a system of levers or othersimilar connections it follows as a matter of course that the rebound isvery much more severe than when a direct connection is provided, as inmy invention, for such system of interme- 0 diate levers or otherconnections in order to be effective must be and is of very considerableweight. By my invention I provide, as I have found by actual use, a veryeffective baling device of much less weight than the 3 5 machines ingeneral use and one inwhich the jar and shock incident to the reboundreferred to is greatly diminished.

By arranging the pull-bar below the longitudinal center of the bottomof' the baling- 0 case and connecting it, as shown, to the head I amenabled to get a very direct and effective pull Without any liability oftwisting or otherwise distorting the parts, and by the provision of theraised central portion 10 of the said 5 slide I am enabled to so closethe slot in the bottom of the baling-case as to leave no objectionableridge or rib on the finished, bale, asmight be the case if the hay werefree to be forced down through such slot.
